Plugin

not creatable

Plugin is the main object responsible for creating basic studio widgets. It is a custom add-on to Studio which adds new behavior and features that are not normally included.

Summary

Properties

  • read only
    not replicated
    read parallel

    Returns whether the user enabled Collisions in studio under the Model tab.

  • read only
    not replicated
    read parallel

    Returns the grid size the user has set in studio under the Model tab.

Properties

CollisionEnabled

read only
not replicated
read parallel

Returns whether the user enabled Collisions in studio under the Model tab.

GridSize

read only
not replicated
read parallel

Returns the grid size the user has set in studio under the Model tab. This can be 1, 0.2 or 0.01, but has rounding errors. The 1/5th option should return 0.2, but could return 0.20000000298023 instead. This code can be used to get the real gridsize:


local gridsize = plugin.GridSize
if math.abs(gridsize-0.2) < 0.005 then -- Check if the gridsize is between 0.195 and 0.205
gridsize = 0.2
elseif math.abs(gridsize-0.01) < 0.005 then -- Between 0.005 and 0.015
gridsize = 0.01
else -- Assume it's 1
gridsize = 1
end

Methods

Activate

void

This function sets the state of the calling plugin to activated. Activating the plugin allows mouse control through the Plugin:GetMouse() method.

At any given time there are either 0 or 1 Activated Plugins. Activating a plugin will deactivate all other plugins (they will receive a Plugin.Deactivation event).

See also:

  • Plugin:IsActivatedWithExclusiveMouse(), returns true if this plugin is currently active with an exclusive mouse, after having been activated via this function
  • Plugin.Unloading, fires immediately before the plugin is unloaded or reloaded via uninstallation, deactivation, or updating

Parameters

exclusiveMouse: bool

A boolean specifying whether to activate the plugin with exclusive mouse. If true, a PluginMouse can be retrieved via Plugin:GetMouse().


Returns

void

CreatePluginAction

This function creates a PluginAction which is an object that represents a generic performable action in Roblox Studio, with no directly associated Toolbar or Enum.Button. In Roblox Studio, they can be assigned a keyboard shortcut under File → Advanced → Customize Shortcuts…, and they can also be added to the Quick Access Toolbar.

When an action is triggered, the PluginAction.Triggered event is signaled.

In order for PluginActions work as expected, they must be created using this function.

See also:

Parameters

actionId: string

Must be a unique string that identifies this PluginAction from others.

text: string

The displayed name of the action.

statusTip: string

The displayed description of the action.

iconName: string

The name of the icon used to display the plugin.

Default Value: ""
allowBinding: bool

Whether the PluginAction will be hidden from Studio's shortcuts view. Useful for contextual actions. Defaults to true.

Default Value: true

Returns

local pluginAction = plugin:CreatePluginAction(
"HelloWorldAction",
"Hello World",
"Prints a 'Hello world!'",
"rbxasset://textures/sparkle.png",
true
)
pluginAction.Triggered:Connect(actionTriggered)

CreatePluginMenu

This function creates a new PluginMenu, which is a context menu that can be shown in Studio that displays a list of PluginActions and supports submenus.

In order for PluginMenus to work as expected, they must be created using this function.

See also:

Parameters

id: string

Unique ID for the menu.

title: string

The text to be displayed when used as a sub menu.

Default Value: ""
icon: string

ImportFbxAnimation

yields

This function prompts the user to open a .fbx animation file that can be loaded onto the rigModel, then proceeds to insert the animation as a KeyframeSequence in the Workspace.

Parameters

rigModel: Instance
isR15: bool
Default Value: true

Returns

ImportFbxRig

yields

Prompts the user to open a .fbx file, uploads the individual components of the model as meshes, and generates a character rig for use in animation, which is loaded into the Workspace.

Parameters

isR15: bool
Default Value: true

Returns

PromptForExistingAssetId

yields

Opens a window in Roblox Studio, which prompts the user to select an asset based on the assetType specified. Returns what assetId was selected, or -1 if the window was closed.

Parameters

assetType: string

Returns

PromptSaveSelection

yields

Prompts the user to save their current selection with the specified file name. Returns true if the user did save the file.

Parameters

suggestedFileName: string
Default Value: ""

Returns

Events

Deactivation

Fired when the Plugin is deactivated. This occurs when either the plugin code calls Plugin:Deactivate(), or because some other plugin called Plugin:Activate(), which forces all other plugins to lose their active state.

See also:

  • Plugin.Unloading, fires immediately before the plugin is unloaded or reloaded via uninstallation, deactivation, or updating

Unloading

This event fires immediately before the Plugin stops running. Plugins are unloaded when disabled, uninstalled, about to be updated, or when the place is closing.

It enables a plugin to clean up after itself before its scripts stop running, e.g. to remove unnecessary instances from the DataModel. If a plugin does not clean up properly, the old copies will remain. When this occurs, users may be forced to close and reopen the place which is a bad user experience.

Plugin-related instances such as PluginToolbarButtons, DockWidgetPluginGuis, and PluginGuis are automatically cleaned up when the plugin is unloaded so there is no need to remove them.
